How to write efficient SQL |
If you want to write an efficient query, you need to be familiar with the data, metadata, and the intent of the query. In this presentation we will discuss the information you need to know (or collect), and then explain how knowing this information will allow you to construct a "picture" of your query that allows you to identify the most efficient route to your final result. |
